Designed specifically for finance and accounting work, this 18-key wired numeric keypad features both USB and USB-C interfaces for plug-and-play use with a wide range of devices. Important system compatibility note: On Windows, all keys and hotkeys work seamlessly. On macOS and iOS, the numeric keys and the + - * / symbols function perfectly, but due to system limitations, hotkeys such as Numlock, Home, End, PgUp, PgDn, and the arrow keys are not supported; this does not affect standard number entry and calculation on Apple devices. Whether you are working from home, on the move, or performing everyday calculations, it is a reliable tool for boosting your numeric data entry efficiency.
